T 0 all whom it may concern: 5

Be it known that I, ARTHUR R. SELDEN, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of New Yorkhave invented certain new and useful Improvements in'Loose-Leef Binders,of which the following is a specification. i

The present invention relates "to loose leaf binders and an objectthereofis to provide a binder employing two binder members, each ofwhich has a cover hinged thereto and impaling projections, all combinedwith Inez-ins for locking the members together. A further object of theinvention is to provide a binder having alocking means of novelconstruction whicl'r will hold two binder members infirm connection. Astill further object of the invention is to provide :1 leaf tighteningmeans in connection with an impaling means "which will prevent themovement of the leaves on the impaling means during the use of thebinder. i further object oi? the invention is to provide in connectionwith a locking means for holding two binder members together, a leaftightening means controlled simultaneously with said locking means. a Tothese and other ends the invention consists oi certain parts andcombination of ports, all of which will be hereii'iafter do scribed, thenovel features being pointed out in the appended claims.

referring more particularly to the draw ings, lindicates one of thebinder members and 2 the other. Associated with these binder members isen inipaling means consisting, in this instance, of pins '3 arranged onthe binder member lend P111811- arranged onthe binder member 2; EachlJlIlClQPlilGllb her also has )re'terablya cover 5 hinged thereto at 6.oclrets or openings .7 may be provided in the binder membersland E2 inwhich the ends of the impaling pins 3 and at may extend asshown in Fig.11. -Each binder member may also have a book casing 8 secured theretoand cooperating with the casing of the other member in order to providea chamber in rear of the impa'ling nicans. Theopposed faces of thebinder members 1 and-2 form rests or engagingsurfaces for the leaves 9,each of which is, in this instance, provided with openings 10 for theimpeling pins 3 and openings 11 for the impaling'pins d. t apparent thatthe leaves will b'e held between the two binder members when the letterare associated together and when the binder members are sepnratm theleaves may beheld on either binder member through theimpalin pins onsuch member,- thus permitting the leaves to be transferred one at a timefrom one binder member toithe other and at the same time permitting theleaves on the two members to be brought together, due to the fact thatthe openings in i'heleaves on any one member 'tvillbe properly alir forlt-JCfilV- ing the iin 'ialing pins on the other, member.

His desirable to provide some meansifor securely holding the bindermembers together. binder member l is providedwith an elon gatedprojection 12 preferably formed in one piece with the bindermember 1 andpro j ected laterally withre'ference toassid binder member. Thisprojection is adapted for co operation with a clamp. carried by thebinder member 2. The clamp in the present embodiment comprises twoclamping members 13 and 1d. The clampingmember 18 is,

' in thisinstance formed bv a'olete bent lat erslly tronvthestripotshect metal pro viding the binder membeixEZV Thisplate has spacedopenings 15 ther in formed by cutting the metal zindto provide tongues16' which are bent rearwardlyirom suchplste. The clamping member lt'isin the form o a lVithQ- this purpose in viewythe I I U shaped striphaving its ends 17. extended through the openings 15 into parallelrelation with the tongues 16., The projection 12 Movement of theoperating rod 18 in one direction moves'the clamping member 14'towardtheclamping member 1 3, while operation of the rod in the oppositedirection moves the clamping member 14 away from the clamping member13.3 Longitudinal movement of the rod in the tongues 16 may be preventedby pins orprojections 20 and these pins also serve as stops for limitingthe rotary movementof the rod in two directions. This rod lies in thechamber formed bythe back casings. 8 and has one end 6X- tending to theexterior of the casing and provided with a slot 21 in which a coinorother instrument may be introduced forthe purpose of effecting theturning of "the Y rod 18.

' mounted on the binder member 2.. The '65 Loose leaf binders whichsecure the leaves through impaling means extending through openings inthe leaves require that such openings be materially larger than the imspalingprojections in order to facilitate the movement of the leaves onsuch projections.

As a consequence, there is a tendency for the leaves to shift ontheimpaling projections or pins slightly and this interferes with theturning of the leaves one at a time. According to this invention, aleaf-tightening means is provided which will shift the leaves intheirplanes into binding engagement with the impaling pins ,or projections.

This leaf-tightening meansjin this in stance, comprises two tighteningdevices 00- operating preferably with the edges of the sheets adjacentthe impahng pins or project tions 3 Land 4; The sheets,-inthis'instance,

are formed with V-shaped notches22 situ-j atedbetween the openings 10and lland the leaf tightening devices cooperate withthe walls of thesenotches and .force the leaves in their planes against the impaling pins3 and 4,'while at the same time preventingmovement of theleavesin thedirection of the line of the centers of the openings 10 and 11. Eachleaf-tightening device comprises, in this instance, a member 23 rigidlysecured to the binder member 1 and a member- 24 member 24 is formedofsheet metal bent between its ends to provide a wedge shaped portion 25which may be readily introduced in the'notches 22 of the leaves. Theportion 25 is coextensive with the distance between the leaf engagingfaces of the binder members 1 and 2, and the upper part thereof' isnotched at 26 to receive the member 23 while its lower end is providedwith a I guide pin or projection 27 adapted to operate in a slot 28 inthe binder member 2, the member 23 operating to prevent leavespassing-over the upper end of the portion 25 and the prcj ection 27operating to prevent leaves passing under the lower end of said portion.

The ends of the metal piece forming the member 24 are bent into parallelrelation at 29 to provide a projection, these ends hav ing registeringopenings 30 through which the operating rod 18 extends. The operating'rod hascam portions 31 thereon in the form of eccentric surfaces whichcoeperate with the walls of the openings 30 in the two tighteningdevices. When the rod is turned in order to clamp the projection 12"between the clamping members 13 and 14, the memhere 24 of thetightening deviceswill be shifted outwardly into binding engagementwiththe walls of the notches 22 of the leaves '9. In this movement the'members 24' are.

guided by the walls of slots 32 formedin the supporting plate 13 of thebinder member 2, such slots 32 being sufficiently large to permit playof the members 24 in order that the latter may be properly centered withrespect to the notches 22. When the members 24 move into bindingengagement with the walls of the notches 22, they shift the leaves intheir planes into binding engagement with the impaling plnsor posts 3and 4 and this blndmg engagement together with the binding engagementwith the tapering faces 25 of the members 24 holds the leaves againstany loose movement on the impaling pins or projections.

The shaft or operatingrod 18 is referably inclosed by a cas1ng33, inthis in stance, in the form of a channeled piece having its edgessecured by screws 34 to the plate-13 above and below the shaft. By thisarrangement, when the two binder members are separated, the shaft andcooperating parts inclosed by the casing 33 are hidden fromview."

In using the binder, assumingthat the latter is closed or locked in themanner shown in Fig. 9, the shaft 18 is turned to release the projection12 from the clamping plates 132'and 14 and to 'move the members 7 24 ofthe leaf tightening means inwardly, J 1

thus simultaneously unlocking the leaves and the binder members. Theupperbinder member 1 may then be elevated with'refen.

ence to the lowerb inder member 2 and as many leaves as desired removedwith said upper binder member, due to the fact that paling pins of eachmember are introduced 7 into the openings ofthe leaves in the othermember and after the members are properly coupled together the shaft 18is turned, thus clamping the projection 12' and at the same tlme lockingthe leavesthrough the movable leaf tightening members 24.

From the foregoing it will be seen that there has been provided a looseleaf binder having two binder members, each of which has a cover hingedthereto and each of which has impaling projections extending there--from. A novel means is provided for locking these binder memberstogethenthis means preferably being in the form of a projection on oneof the binder meinbers operating between a movable and a fixed clampingmember on the other binder memher. The clamping members are controlledby a shaft or rod lying to one side of the leaves and operable from theexterior of the binder. There has also been provided means fortightening the, leaves in the binder to prevent any loose movement ofthe leaves on the impaling means. This tightening means shifts theleaves in their plane into binding engagement with the impaling meansand also interlocks with the leaves to prevent sidewise movement of thelatter. In this instance, this leaf tightening means is controlled bythe operating member for locking the two binding members together.
